Abstract: A fuel vapor management system for an automotive vehicle includes a vapor tower in fluid communication with a vapor purge outlet of a fuel pump. A fluid treatment section, such as a screen, is disposed between the fuel pump vapor purge outlet and the vapor tower. The fluid treatment section reduces the size and momentum of purged vapor bubbles such that the purged vapor bubbles in the vapor tower may rise in the vapor tower and separate from liquid fuel thereby, allowing liquid fuel to flow out of the vapor tower and allowing fuel vapor to escape from the vapor tower away from the inlet of the fuel pump inlet.

Abstract: A point-type radio controller using infrared rays facilitates an installation of a receiving sensor by arranging an infrared transmitter and an infrared receiver at right angle to each other, and accurately computes a coordinates-position of a designated point through double calculating coordinates value of a point in a constant time. The point-type radio controller using infrared rays includes a transmitting means for transmitting an infrared signal having a constant period, and having infrared diodes as a plurality of signal generators in the direction of Y-axis in order to achieve a constant angle; a receiving means for receiving the infrared signal by mounting infrared receiving sensors on a display device at a right angle to the infrared diodes in the direction of X-axis; and a controlling means for calculating coordinates-position of an indicated point by using an intensity difference between the infrared signals received by the receiving means, and displaying a calculated point on a display screen.

Abstract: A method for interfacing electrical signals transmitted between an engine controller and a video controller through first and second transmission lines in an image forming apparatus includes the steps of: transmitting first data indicating an engine power ready state from the engine controller to the video controller through the first transmission line when power is initially supplied to the engine controller, transmitting second data representive of a print ready state from the engine controller to the video controller through the first transmission line after performing a warm up operation on the image forming apparatus, transmitting third data representing commencement of a printing operation from the video controller to the engine controller through the second transmission line in response to an input of printing data to the video controller from an external source, transmitting fourth data representative of a request for page synchronization information from the engine controller to the video controller

Abstract: A system for automatically eliminating a paper jam in an electrophotographic device may be initiated by removing and re-inserting a paper cassette subsequent to the occurrence of the paper jam. If the paper cassette is removed and inserted, a paper jam eliminating mode is implemented to eliminate the paper jam.

Abstract: A power-saving printing method that wakes up an image-forming device prior to a print operation in order to reduce an extended print time resulting from a warm-up period of the device. One embodiment of the method includes the steps of: establishing a power-saving mode when the image-forming device has not received a print code for a predetermined period of time, determining whether a wake-up control code is included in a received print code, performing a wake-up operation and establishing a print ready state when the warm-up control code is included, and performing an operation corresponding to the received print code after the wake-up operation is performed when the wake-up control code is not included.

Abstract: A method for forming an isolation region within a semiconductor device is disclosed. A trench is first formed in a predefined isolation region of a semiconductor substrate. An oxidation blocking material is injected into the inside walls of the trench before growing a field oxide film inside the trench. Accordingly, the present invention can simplify the fabrication of isolation regions within a semiconductor device by directly implanting the oxidation blocking material at a predetermined angle into the inside walls of the trench which constitutes the isolation region. In the present invention, unlike conventional fabrication processes using spacers to prevent penetration of a field oxide film into the surface of semiconductor non-isolation regions, the need for spacers is obviated.

Abstract: In an element isolation method of a semiconductor device which can form an element isolation region having a flat surface without regard to the width of the element isolation region, and whose width is below the resolution limit, an insulating film having an aperture in order to define the element isolation region is formed on the semiconductor wafer, wherein an oxidizable material layer is deposited and then first spacers are formed on the sidewalls of the aperture. Then, a thermal oxide film is formed over the entire semiconductor wafer, excluding a first-spacer-formed region, and the first spacer is removed. The wafer surface is exposed to the lower part of the removed first spacer region, and then the portion of the semiconductor wafer below the exposed region is etched to thereby form a trench. After that, an element isolation region is formed by filling up the trench and removing the insulating film around tile trench.

Abstract: An isolation method in a semiconductor device which includes the steps of growing a pad oxide layer on a semiconductor substrate, depositing a polysilicon layer and a first silicon nitride layer on the pad oxide layer, removing and patterning the first silicon nitride layer to define an active region and a field region, depositing a second silicon nitride layer and a thick oxide layer, forming oxide spacers and nitride spacers, ion-implanting impurities, removing the oxide spacers, growing a field oxide layer, and sequentially removing the first silicon nitride layer, the nitride spacers, the polysilicon layer, and the pad oxide layer. This method minimizes the bird's beaks regions and increases the effective isolation distance of the device.
